General information<br />

Refer to the front of this manual for general test conditions,<br />

terminology, detailed descriptions of wiring faults and a<br />

general trouble shooter for electrical and mechanical faults.<br />

<strong>Trouble</strong> codes are displayed by the four wheel drive warning<br />

lamp.<br />

D The four wheel drive control module fault memory can also<br />

be checked using diagnostic equipment connected to the<br />

data link connector (DLC).<br />

Accessing - +07/93<br />

Ensure ignition switched OFF.<br />

Bridge data link connector (DLC) terminals A and J El.<br />

Switch ignition ON.<br />

Count four wheel drive warning lamp flashes. Note trouble<br />

codes. Compare with trouble code table.<br />

Each trouble code consists of two groups of one or more<br />

flashes.<br />

The first group of flashes indicate the 'tens' of the trouble<br />

code [A].<br />

The second group of flashes indicate the 'units' of the<br />

trouble code 8 [Dl.<br />

A short pause separates each trouble code group 8 [C].<br />

A long pause separates each trouble code 8 [El.<br />

For example: <strong>Trouble</strong> code 31 displayed 8.<br />

Each trouble code including 12 displayed three times.<br />

Erasing - +07/93<br />

Switch ignition OFF.<br />

Remove bridge wire from data link connector (DLC)<br />

terminals A and J 8.<br />

Cycle ignition switch ON and OFF 16 times to erase trouble<br />

codes.<br />

Repeat checking procedure to ensure no data remains in<br />

four wheel drive control module fault memory.<br />

Accessing and erasing - 08/93 +<br />

The four wheel drive control module fault memory can only<br />

be accessed and erased using diagnostic equipment<br />

connected to the data link connector (DLC).
